基于 MCGS 组态软件的 CP 监测仪监控软件的实现
摘 要
软件 PLC，即将 PLC 的控制功能封组在软件内，运行于 PC 环境中。这样在
实现传统硬 PLC 相同的功能的同时，更添加了 PC 机的各个优点。与传统硬 PLC
相对比，软 PLC 数据处理能力和网络通讯能力更强，体系结构更加开放，能够更
好地满足工业自动化的现实需求，在当前工业自动化领域具有无限的发展空间和
潜力。
本文在对软 PLC 应用及优势等背景进行分析的基础上，以基于 MCGS 组态软
件的 CP 监测仪监控软件的实现为例子，实现了基于 PC 的软 PLC 系统设计。文章
首先对软 PLC 技术的背景和发展现状以及本选题的研究目的和意义进行了分析，
然后对 CP 监测仪的相关知识做了详尽的介绍，接着分析了 CP 监测仪的组态监测
系统设计，最后基于 MODBUS 协议实现了上位机系统与下位机系统地连接，并进
行了测试。

The Realization of Monitor Software for CPMS
based on MCGS
Abstract
Software PLC,is the technology that seal group PLC control
functions in the upcoming software running on a PC environment.Thus
while achieving the same functionality of traditional PLC
hardware,but also add the various advantages of the PC.In contrast
with traditional hard PLC, Soft PLC data processing and network
communications capabilities become stronger, have more open
architecture that can better meet the real needs of industrial
automation, with unlimited space and potential for development in the
current field of industrial automation.
Based on analyzing the applications,advantages and other
background of soft PLC，in order to achieve MCGS configuration software
based on CP monitor monitoring software as an example, it achieves a
PC-based soft PLC system design.Firstly,the the article introduces
the status of the background and development of soft PLC technology
and research purpose and significance of the topics, and then makes a
detailed presentation of monitor the relevant knowledge of CP ,
followed by analysis of the CP Monitor Configuration Monitoring
System.Finally, based on MODBUS protocola,the host computer system
and lower computer systems connected and tested.
Keywords:Soft PLC; MCGS configuration software; CP monitor;
monitoring software
